My question is this... is there any way to determine if the ExceptionHandling block has been configured? I ask because, if this method is called from a unit test that is testing the DAL or business layer, it likely wouldn't have access to our web.config
file.

If the config file doesn't exist, then when an exception is thrown, our exception is replaced with an ExceptionHandlingException thrown by the block because it is not configured.

What is the best pattern to work around this, without having to duplicate the config file?
